Revert r87049, which was the workaround for the regression triggered
by the recent FixedStackPseudoSourceValue-related changes, now that
the specific bug that affected it is fixed, in r88954.

Revert the test from r88984. It relies on being able to mmap 16GB of
address space (though it only uses a small fraction of that), and the
buildbots disallow that.

Also add a comment to the Makefile's ulimit line warning future
developers that changing it won't work.

Make X86-64 in the Large model always emit 64-bit calls.
The large code model is documented at
http://www.x86-64.org/documentation/abi.pdf and says that calls should
assume their target doesn't live within the 32-bit pc-relative offset
that fits in the call instruction.

To do this, we turn off the global-address->target-global-address
conversion in X86TargetLowering::LowerCall(). The first attempt at
this broke the lazy JIT because it can separate the movabs(imm->reg)
from the actual call instruction. The lazy JIT receives the address of
the movabs as a relocation and needs to record the return address from
the call; and then when that call happens, it needs to patch the
movabs with the newly-compiled target. We could thread the call
instruction into the relocation and record the movabs<->call mapping
explicitly, but that seems to require at least as much new
complication in the code generator as this change.

To fix this, we make lazy functions _always_ go through a call
stub. You'd think we'd only have to force lazy calls through a stub on
difficult platforms, but that turns out to break indirect calls
through a function pointer. The right fix for that is to distinguish
between calls and address-of operations on uncompiled functions, but
that's complex enough to leave for someone else to do.

Another attempt at this defined a new CALL64i pseudo-instruction,
which expanded to a 2-instruction sequence in the assembly output and
was special-cased in the X86CodeEmitter's emitInstruction()
function. That broke indirect calls in the same way as above.

This patch also removes a hack forcing Darwin to the small code model.
Without far-call-stubs, the small code model requires things of the
JITMemoryManager that the DefaultJITMemoryManager can't provide.

Thanks to echristo for lots of testing!

Do not merge jump tables this early. Branch folding will do any necessary
merges, and until then, it's useful to keep the tables separate for ease
of manipulation.

Cleanup flow, and only update the jump table we're analyzing when replacing a destination MBB.

Add XCore support for arbitrary-sized aggregate returns.

Temporary disable the error - it seems to be too conservative.

Implement DISABLE_INLINE for MSVC. This required changing the position in all
forward declaration and patching tblgen to emit it right. Patch by Amine Khaldi!

This test doesn't work on arm either.

Make NORETURN working with MSVC. MSVC only accepts NORETURN in front of the
decl so move it there. GCC accepts it both in front and after decls.

Add llvm::sys::getHostCPUName, for detecting the LLVM name for the host CPU.
 - This is an initial step towards -march=native support in Clang, and towards
   eliminating host dependencies in the targets. See PR5389.

Remove LLVMContext from reassociate. It was threaded through every function but
ultimately never used.

Teach BasicAA that a constant expression can't alias memory provably not
allocated until runtime (such as an alloca). Patch by Hans Wennborg!

Added getSubRegIndex(A,B) that returns subreg index of A to B. Use it to replace broken code in VirtRegRewriter.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88753 91177308-0d34-0410-b5e6-96231b3b80d8

- Change TargetInstrInfo::reMaterialize to pass in TargetRegisterInfo.
- If destination is a physical register and it has a subreg index, use the
  sub-register instead.
This fixes PR5423.

Add an option for running GVN with redundant load processing disabled.

Fix bug in -split-phi-edges.

When splitting an edge after a machine basic block with fall-through, we
forgot to insert a jump instruction. Fix this by calling updateTerminator() on
the fall-through block when relevant.

Also be more precise in PHIElimination::isLiveIn.

Added an API to the SlotIndexes pass to allow new instructions to be inserted into the numbering.

PreAllocSplitting is now using this API to insert code.

Print out something, even if it's non-parseable later when we've
got ghost linkage. It's better than aborting.

Move the FixedStackPseudoSourceValueVal enum value before InstructionVal
so that isa<Instructon> doesn't return true for FixedStackPseudoSourceValue
values. This fixes a variety of problems, including crashes with -debug
and -print-machineinstrs. Also, add a comment to warn about this.
